A Double Layer Beam Shaping Assembly (DLBSA) was designed to produce epithermal neutrons for BNCT purposes. The Monte Carlo N-Particle eXtended program was used as the software to design the DLBSA and phantom. Distribution of epithermal neutron and gamma flux in the DLBSA and phantom and absorbed dose in the phantom were computed using the Particle and Heavy Ion Transport code System program. Testing results of epithermal neutron beam irradiation of the water phantom showed that epithermal neutrons were thermalized and penetrated the phantom up to a depth of 12 cm. The maximum value of the absorbed dose was 2 × 10-3 Gy at a depth of 2 cm in the phantom.

“…Boron Neutron Capture Therapy (BNCT) is a method for cancer therapy which irradiates cancer cells previously injected with boron 10 B. Interaction of a thermal neutron and a 10 B nucleus will form a compound nucleus 11 B. The compound nucleus will subsequently decay, radiating gamma and alpha particles.…”

“…To have an optimal radiation beam from the BSA, optimization is required about configurations of components that constitute the BSA, in a graduated or step-by-step way [9,11]. However, graduated optimization most frequently does not yield radiation beams as required by the IAEA.…”

“…Other achievements in the application of GA are the determination of optimum thickness in moderator design [15] and gamma shielding design to determine the best composition of some materials [16]. The latest achievement is the use of Multi-Objective Genetic Algorithm (MOGA) and Monte Carlo optimization method in optimizing the beam port of ITU reactor to produce epithermal neutron beams for BNCT purposes [11].…”

The genetic algorithm method is a new method used to obtain radiation beams that meet the IAEA requirements. This method is used in optimization of configurations and compositions of materials that compose double layered Beam Shaping Assembly (BSA). The double layered BSA is modeled as having two layers of material for each of the components, which are the moderator, reflector, collimator, and filter. Up to 21st generation, the optimization results in four (4) individuals having the capacity to generate the most optimum radiation beams. The best configuration, producing the most optimum radiation beams, is attained by using combinations of materials, that is by combining Al with either one of CaF2 and PbF2for moderator; combining Pb material with either Ni or Pb for reflector; combining Ni and either FeC or C for collimator, and FeC+LiF and Cd for fast and thermal neutron filter. The parameters of radiation resulted from the four configurations of double layer BSA adequately satisfy the standard of the IAEA.
